asyncio (PEP 3156) Redis support

Project description

asyncio (PEP 3156) Redis client library.


hiredis parser Yes
Pure-python parser TBD
Low-level & High-level APIs Yes
Connections Pool Yes
Pipelining support Yes
Pub/Sub support Yes
Redis Cluster support WIP
Trollius (python 2.7) No
Tested python versions 3.3, 3.4, 3.5
Tested for Redis server 2.6, 2.8, 3.0
Support for dev Redis server through low-level API

Usage examples

Simple low-level interface:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

def go():
    conn = yield from aioredis.create_connection(
        ('localhost', 6379), loop=loop)
    yield from conn.execute('set', 'my-key', 'value')
    val = yield from conn.execute('get', 'my-key')
# will print 'value'

Simple high-level interface:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

def go():
    redis = yield from aioredis.create_redis(
        ('localhost', 6379), loop=loop)
    yield from redis.set('my-key', 'value')
    val = yield from redis.get('my-key')
# will print 'value'

Connections pool:

import asyncio
import aioredis

loop = asyncio.get_event_loop()

def go():
    pool = yield from aioredis.create_pool(
        ('localhost', 6379),
        minsize=5, maxsize=10,
    with (yield from pool) as redis:    # high-level redis API instance
        yield from redis.set('my-key', 'value')
        print((yield from redis.get('my-key')))
    yield from pool.clear()    # closing all open connections




hiredis is preferred requirement. Pure-python fallback protocol parser is TBD.


The aioredis is offered under MIT license.


0.2.4 (2015-10-13)

  • Python 3.5 async support:
    • New scan commands API (iscan, izscan, ihscan);
    • Pool made awaitable (allowing with await pool: ... constructs);
  • Fixed dropping closed connections from free pool (see #83);
  • Docs updated;

0.2.3 (2015-08-14)

  • Redis cluster support work in progress;
  • Fixed pool issue causing pool growth over max size & acquire call hangs (see #71);
  • info server command result parsing implemented;
  • Fixed behavior of util functions (see #70);
  • hstrlen command added;
  • Few fixes in examples;
  • Few fixes in documentation;

0.2.2 (2015-07-07)

  • Decoding data with encoding paramter now takes into account list (array) replies (see #68);

  • encoding parameter added to following commands:

    • generic commands: keys, randomkey;
    • hash commands: hgetall, hkeys, hmget, hvals;
    • list commands: blpop, brpop, brpoplpush, lindex, lpop, lrange, rpop, rpoplpush;
    • set commands: smembers, spop, srandmember;
    • string commands: getrange, getset, mget;
  • Backward incompatibility:

    ltrim command now returns bool value instead of ‘OK’;

  • Tests updated;

0.2.1 (2015-07-06)

  • Logging added (aioredis.log module);
  • Fixed issue with wait_message in pub/sub (see #66);

0.2.0 (2015-06-04)

  • Pub/Sub support added;
  • Fix in zrevrangebyscore command (see #62);
  • Fixes/tests/docs;
